Congrats are in order for Chris Pratt and Katherine Schwarzenegger!

The Guardians of Galaxy actor revealed on Instagram early this morning (Jan. 14) that he and Schwarzenegger are engaged to be married after seven months of dating.

"Sweet Katherine, so happy you said yes! I’m thrilled to be marrying you. Proud to live boldly in faith with you. Here we go!" the 33-year-old lovingly captioned the photo that sees the couple with their wraps around one another as Schwarzenegger admires her massive diamond engagement ring. FYI: The rock is HUGE!

The pair first sparked dating rumors last June after they were spotted having a picnic on Father's Day. Since then, they've kept their relationship on the DL, rarely posting photos of one another on social media. Pratt did, however, confirm their romance in December after he shared the sweetest tribute to celebrate Schwarzenegger's birthday.

"Your smile lights up the room," he wrote alongside a collage of sweet moments they've shared over the year. "I’ve cherished our time together. Thrilled God put you in my life. Thankful for the laughs, kisses, talks, hikes, love and care."

Congrats again to these two lovebirds!
